Characterization of Multiferroic Domain Structures in Multiferroic Oxides

Figure 7

Morphology of charge-ordered domains in LuFe₂O₄ [26]. (a) SAED pattern of LuFe₂O₄ recorded at 299 K. (b) Dark-field TEM image of the charge-ordered domains obtained by using the diffuse scattering indicated by the circle in the inset. The charge-ordered domains are imaged as bright dots. (c) Nanometer-scale bright dots (indicated in red) representing the charge-ordered domains, which are used to determine the average spacing between the neighboring charge-ordered domains.
